    摘要: A circuit for flash equipment having a trigger control switch or an SCR with its gate lead connected to a condenser through a switching transistor which is rendered conducting when the main flash capacitor is charged to the normal firing voltage and when the X sync contact is closed. After a time interval from the closure of the X sync contact, the condenser is short-circuited to prevent refiring of the flash tube. Such refiring would otherwise be caused when the condenser is recharged to actuate the SCR during the period of closure of the X sync contact.

    摘要: A motor drive unit for a camera having variable winding speed characteristics functions so as to operate in a manner suited to environmental conditions such as temperature. This is done by changing the gear ratio from the motor to one of two values near the point of maximum efficiency and the point of maximum power output of the characteristic curve of the motors. Timer-controlled change of film frequency variation for providing a combined effect with the gear ratio is also disclosed.

    摘要: In the disclosed camera, a manually operated film advance lever and a shutter button are arranged conveniently to be operated when the camera is held for a horizontal shot, i.e., an exposure during which the film frame is oriented horizontally. A coupling arrangement, in an adapter suitable for mounting on the camera, engages a camera film winder and shutter release and contains a second winding lever and a second shutter release button both oriented in a position suitable for taking a vertical shot.

    摘要: In the disclosed arrangement, an energy storage device such as a capacitor is discharged through a flash lamp. A sensing device produces a signal when the storage voltage is sufficient to fire the lamp. A switchover device normally permits the shutter and exposure aperture to be set for daylight operation, but automatically responds to the signal to switch the shutter speed and the exposure aperture to suitable values for flash operation.

    摘要: The device includes a permanent magnet for attracting a movable iron armature. A pair of elongated rectilinear magnetic bodies have planar pole faces at one end facing the iron armature, and the permanent magnet is sandwiched between these two magnetic members intermediate their ends, with the permanent magnet extending perpendicularly to the magnetic members. Respective magnetizing windings embrace each magnetic member between the permanent magnet and the pole faces of the members, to produce a magnetic flux in the magnetic members opposing the flux provided by the permanent magnet so as to release the iron armature. In one embodiment of the invention, the other ends of the members, projecting beyond the permanent magnet, are angled to face each other to provide an air gap therebetween. In a second embodiment of the invention, the magnetic members or yokes have respective second windings thereon, beyond the permanent magnet, and the ends of these yokes, beyond the second windings, are formed with planar pole faces for operative association with a second iron armature. Both iron armatures are spring biased to disengage the magnetic yokes or members. As the permanent magnet engages the yokes intermediate their ends, the magnetic flux path due to the magnetizing windings does not include the permanent magnet and therefore an effective armature releasing magnetic flux can be provided with only a relatively small current supplied to the magnetizing windings.

    摘要: A co-ordination control system for a camera and a motor drive unit with separate electrical power sources one of which has a higher voltage than the other. The system is provided with an interface circuit including two switching elements arranged to cooperate with a common release button and connected between the circuitries of the camera and the unit so that the higher voltage of the source in the unit is prevented from being applied to the circuitry of the camera. For remotely controlled photographic purposes, the system is further provided with a control circuit for actuating these two switching elements in time-displaced relation to each other.
